Acup of hot water cannot melt a large block of ice. however, the same block melts when dropped into a lake. this is because
a) the lake is at a lower temperature than the cup of hot water.
b) the lake is at a higher temperature than the cup of hot water.
c) the lake contains less mass and heat than the cup of hot water.
d) the lake contains more mass and more heat than the cup of hot water.

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
